Embodiment Construction

[0024] The content of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] Such as figure 1 As shown, a vacuum perfusion guide tube includes a guide tube main body 2. The guide tube main body 2 described in the present invention is a pipe with a cylindrical structure, and then from one end of the pipe with a cylindrical structure along the length of the pipe The pipe body cut out in the direction, this pipe body is the diversion pipe main body 2 of the present invention. The description above is split to facilitate the understanding of those skilled in the art. In fact, the bottom plate 1 and the main body of the draft tube 2 in the present invention are integrally formed, and the bottom plate 1 and the main body of the draft tube 2 form a whole with a hollow interior. Such as figure 2 As shown, the bottom plate 1 is equidistantly provided with a plurality of diversion holes 3 along the extending direction ...

Abstract

The invention relates to a flow guide pipe for vacuum filling and a preparation method thereof. The flow guide pipe comprises a flow guide pipe main body, wherein a bottom plate is arranged at the bottom of the flow guide pipe main body, and the flow guide pipe main body and the bottom plate are integrally molded to form a whole body with a hollow inner part; a plurality of flow guide holes are formed in the bottom plate at equal distances along the extending direction of the flow guide pipe main body; and the flow guide pipe is obtained by putting a mixed material of polypropylene resin and polyethylene resin into an extruder, then extruding the mixed material into a corresponding mold after fusing, and cooling and molding. Compared with the prior art, the flow guide pipe for the vacuum filling, provided by the invention, has the advantages of printing mark prevention, capability of guiding resin at a high speed and the like.

Description

technical field [0001] The invention relates to a structure and a preparation method of a draft tube for vacuum perfusion. Background technique [0002] Among the current materials, composite materials are widely used because of their light weight and high strength. The manufacturing process for composite materials is also constantly improving and innovating. From the initial hand lay-up, to mechanized spraying, pultrusion, molding and other processes, to the emerging vacuum infusion process. [0003] Vacuum infusion process refers to laying reinforcing materials (glass fiber, carbon fiber, sandwich material, etc., different from vacuum bag process) on the mold first, then laying vacuum bags, and extracting the air in the system to form a negative pressure in the mold cavity , use the pressure generated by the vacuum to press the unsaturated resin into the fiber layer through the pre-laid pipeline, let the resin infiltrate the reinforcing material and finally fill the enti...
